What does tachycardia mean in medical terms?
Listen to pronunciation. (TA-kih-KAR-dee-uh) Rapid beating of the heart, usually defined as greater than 100 beats per minute.
What are the two types of ventricular tachycardia?
There are three important types of ventricular tachyarrhythmia: Monomorphic ventricular tachycardia. Ventricular fibrillation (VF) Polymorphic ventricular tachycardia (Torsade de Pointes)
What is salvo in ECG?
– Salvos or increased frequency of ectopic activity. – Bigemeny, which is when every second beat is an ectopic beat. – R on T ventricular ectopics – when the R wave of the ventricular ectopic occurs on the T wave (repolarisation period of the cardiac cycle) of the preceding beat.
What is the difference between tachycardia and ventricular tachycardia?
Tachycardia is a very fast heart rate of more than 100 beats per minute. The many forms of tachycardia depend on where the fast heart rate begins. If it begins in the ventricles, it is called ventricular tachycardia. If it begins above the ventricles, it is called supraventricular tachycardia.
What foods cause tachycardia?
Certain foods might trigger SVT while others are full of minerals that help keep your heart in rhythm….They include:
- Alcohol.
- Caffeine in coffee, chocolate, and some sodas and teas.
- Spicy foods.
- Very cold drinks.
What is the most common cause of ventricular tachycardia?
Sometimes it is not known what causes ventricular tachycardia, especially when it occurs in young people. But in most cases ventricular tachycardia is caused by heart disease, such as a previous heart attack, a congenital heart defect, hypertrophic or dilated cardiomyopathy, or myocarditis.
How do you fix ventricular tachycardia?
Sustained ventricular tachycardia often requires urgent medical treatment, as this condition may sometimes lead to sudden cardiac death. Treatment involves restoring a normal heart rate by delivering a jolt of electricity to the heart. This may be done using a defibrillator or with a treatment called cardioversion.
What are the two types of cardiac monitoring?
Common types of cardiac monitoring systems include:
- Holter Monitor. A Holter monitor is a portable external monitor that includes wires with patches that attach to the skin.
- Event Recorder. An event recorder is a recorder worn on the body for up to 30 days.
- Mobile Cardiac Telemetry (MCT)
- Insertable Cardiac Monitor (ICM)
What is Aberrancy in ECG?
Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.
What is the best medicine for tachycardia?
Beta blockers If you’ve been diagnosed with tachycardia, your doctor may prescribe a beta-blocker. Beta-blockers stop the action of the hormone adrenaline. This can relieve your tachycardia by slowing your heart rate. It can also lower your blood pressure and decrease the stress on your heart.
Can you get rid of tachycardia?
Tachycardia caused by medications or diet will go away quickly, usually within hours, when the chemical that is causing the problem is used up by the body or excreted in the urine. Tachycardia caused by cardiac problems can last a long time.
How serious is ventricular tachycardia?
The ventricles (lower chambers of the heart) are where ventricular tachycardia starts. It is a serious condition because it can lead to ventricular fibrillation, whereby the heart no longer pumps blood, leading to sudden death.
What are the different types of ventricular tachycardia?
There are three main types of ventricular tachyarrhythmias: ventricular fibrillation, monomorphic ventricular tachycardia, and polymorphic ventricular tachycardia. Each one is associated with a high mortality rate. Symptoms include chest pain, palpations, hemodynamic collapse, and end-organ damage.
How can ventricular tachycardia be diagnosed?
The most common test used to diagnose ventricular tachycardia is an electrocardiogram (ECG/EKG). An EKG records your heart’s electrical activity. Electrodes (small sticky patches) are placed on your chest and arms to record the heart’s rhythm, and the pattern prints on graph paper.
What medications cause ventricular tachycardia?
Medications. Certain drugs can cause your heart to beat faster. Drugs that extend QT interval such as class III antiarrhythmics and levofloxacin can cause ventricular tachycardia. Other drugs such as halothane that decrease the conduction velocity may also cause your heart to beat faster.
